Description

A kind of D2D resource allocation methods and device

Technical field

The present invention relates to D2D field of communication technology more particularly to a kind of D2D resource allocation methods and device.

Background technique

Allow directly to carry out device-to-device (Device to Device, D2D) between equipment and equipment close to each other It communicates (communication).For ease of description, the link for defining direct communication between D2D terminal is known as D2D link, net Cellular communication link between network and D2D terminal is referred to as equipment to network (Device to Network, D2N) link.

D2D terminal can carry out the distribution of the D2D communication resource by the way of self-organizing.With the ALOHA of reliable communication For (Reliable Reserved ALOHA, RR-ALOHA) algorithm, RR-ALOHA is based on time division multiple acess (Time Division Multiple Access, TDMA) access and resource allocation mechanism.In RR-ALOHA mechanism, each node (example Such as D2D terminal) it must all obtain a primary channel (BC).It, will be periodically at BC pairs after node obtains a BC channel Frame information (Frame Information, FI) and security information are sent in the subframe answered, whether security information is for identifying node For the subframe occupancy situation oneself the directly perceived (jump detected is carried in the legitimate user of network registry, FI The subframe service condition in previous superframe in range).The FI information that each node is sent by monitoring surroundings nodes, according to prison The FI information for the surroundings nodes heard and oneself channel usage timely update subframe occupied state, and by updated son Frame occupied state embodies in the FI information that oneself sends.

It, can be always using occupancy if node does not abandon the corresponding sub-frame resources of BC actively in data transmission procedure Sub-frame transmission data, other nodes cannot use the subframe in the meantime.When the bandwidth that BC is provided is not able to satisfy the requirement of business When, other idle channels can be occupied by way of reserving additional channel transmitted.For point-to-point communication, node can be with It is transmitted by reserving point-to-point (P2P) channel, to realize that adjacent one jumps the subframe multiplexing in cluster, improves the utilization of channel Rate.When message is needed when whole network is broadcasted, RR-ALOHA mechanism can only select limited terminal to be relayed, and avoid Network congestion caused by Flood routing.

If carrying out D2D communication resource distribution using Ad hoc mode, security overhead is excessive, leads to throughput of system very It is low.

The D2D communication resource can also be allocated by base station.If the D2D communication resource is allocated by base station, Transmission security information is not needed, security overhead greatly reduces.But due to the irrelevance of D2N link and D2D link, base station pair D2D communication resource distribution must cause allocation efficiency of resource low dependent on D2D terminal to the feedback of D2D channel conditions.

Specific embodiment

Below in conjunction with attached drawing, technical solution provided in an embodiment of the present invention is described in detail.

Method provided in an embodiment of the present invention the terminal side D2D implementation as shown in Figure 1, specifically including following behaviour Make:

Step 100 is determined by Ad hoc mode resource collision occurs in D2D subframe.

In the embodiment of the present invention, the D2D subframe that node (D2D terminal) occupies is known as D2D and sends subframe, other D2D subframes Referred to as D2D receives subframe.

In the embodiment of the present invention, the subframe for D2D transmission is known as D2D subframe.

Step 110, request base station carry out the control of D2D resource allocation.

Technical solution provided in an embodiment of the present invention, can with but be applicable not only to D2D terminal in the scene of net.

In the embodiment of the present invention, there are many Ad hoc modes of participation D2D resource allocation.For example, existing RR-ALOHA Mode, SU-ALOHA mode, MS-ALOHA mode can also use other Ad hoc modes.

The embodiment of the present invention provides a kind of Ad hoc mode of simplification, which repaired based on RR-ALOHA Change.

The Ad hoc mode of simplification provided in an embodiment of the present invention and the main distinction of existing RR-ALOHA mode are: The state of D2D subframe.Existing RR-ALOHA mode, the state of D2D subframe include: occupied state and idle state.The present invention The Ad hoc mode that embodiment provides, the state of D2D subframe include: to occupy shape body, idle state, strong jamming state and slightly capable and experienced Disturb state.

Wherein, if successfully parsing the letter of the occupancy situation of each D2D subframe in the superframe received in subframe i Breath, but signal strength is lower than given threshold, it is determined that and the state of subframe i is slightly strong jamming；If one received in subframe i The information of the occupancy situation of each D2D subframe can not be parsed correctly in superframe, it is determined that the state of subframe i is strong jamming；Such as Fruit is not received by information in subframe i, it is determined that the state of subframe i is the free time.

Superframe in the embodiment of the present invention can use existing D2D superframe structure, be also possible to the frame knot newly defined Structure, can also be using the wireless frame structure or superframe structure in existing cellular network, and this is not limited by the present invention.

Subframe is received for D2D, the occupancy situation of subframe is specifically codetermined by bottom measurement and MAC layer.Specifically, such as Fruit bottom measurement result shows that subframe i is idle state, then MAC layer is idle (no data can parse), it is thus determined that the shape of subframe i State is idle state；If bottom measurement result shows that subframe i is strong jamming, MAC layer is idle, determines that the state of subframe i is strong Disturbance state；If bottom measurement result shows that subframe is slightly strong jamming, MAC layer is idle, determines that the state of subframe i is slightly capable and experienced Disturb state.

In the embodiment of the present invention, the measurement result of bottom measurement is the total received power and SINR of subframe i.

Wherein, strong jamming is to say to refer to that SINR is not up to thresholding, can not correctly demodulate (it may be no useful signal, It may be that interference is excessive, if reception general power is very high, illustrates there is useful signal certainly, only interfere excessive so solution does not go out Come).

In the embodiment of the present invention, the measurement result of bottom measurement jumps the node occupied just for non-one.

In the embodiment of the present invention, there are many expression ways of receiving intensity.For example, can be indicated using power is received.Compared with Goodly, it is indicated using the ratio for receiving power and signal-to-noise ratio (SINR).

Specifically, the transmission processing of Ad hoc mode provided in an embodiment of the present invention includes: that node is sent in the D2D of oneself When subframe sends data, the information of the occupancy situation of each D2D subframe in a superframe of oneself determination is sent.The information includes Status indicator (information for reflecting subframe state).If the state of subframe i is occupied, strong jamming or slightly strong jamming, shape State is identified as 1, if the state of subframe i is free time, status indicator 0.If status indicator is 1, which further includes node Mark.For occupied state, node identification is the identification information for occupying the node of subframe i；For strong jamming state, node identification It is not the identification information of actual node, but rather indicate that the identification information of strong jamming state, information format both can be with node The format of identification information is identical, can also use extended formatting；For slightly strong jamming state, node identification is not actual node Identification information, but rather indicate that the identification information of slightly strong jamming state, information format both can be with the lattice of the identification information of node Formula is identical, can also use extended formatting.

Specifically, the reception processing of Ad hoc mode provided in an embodiment of the present invention includes:

The occupancy situation of each D2D subframe in the superframe that subframe monitors the transmission of other nodes is received in each D2D Information determines the occupancy situation of each D2D subframe in a superframe according to the information received.

Subframe is sent for the D2D of oneself, is then determined if it is negative-feedback and resource collision occurs, node needs reselect New D2D sends subframe；If it is positive feedback, node continues to safeguard that the D2D sends sub-frame resources.Negative-feedback includes: to receive At least one D2D send subframe occupancy situation information instruction D2D send subframe state be strong jamming state；It receives The information instruction D2D of at least one D2D occupancy situation for sending subframe to send the state of subframe be slightly strong jamming state；It receives The information instruction D2D that at least one D2D arrived sends the occupancy situation of subframe sends the state of subframe as possession state, but node It is identified as the identification information of other nodes.Positive feedback includes: that the information of the occupancy situation of the D2D transmission subframe received indicates The state that D2D sends subframe is idle state；The information that the D2D received sends the occupancy situation of subframe indicates that D2D is sent The state of subframe is strong jamming, and node identification is the identification information of oneself.

Subframe is received for D2D, if the information that D2D receives the occupancy situation of subframe indicates that at least two nodes occupy phase Same D2D receives subframe, determines the D2D to receive in subframe and resource collision occurs；Alternatively, if D2D receives the occupancy feelings of subframe The state that the information of condition indicates that at least one D2D receives subframe is strong jamming state, determines that this at least one D2D is received in subframe Resource collision occurs；Alternatively, if the information that D2D receives the occupancy situation of subframe indicates that at least one D2D receives the shape of subframe State is slightly strong jamming state, determines at least one D2D to receive in subframe and resource collision occurs.

Either RR-ALOHA, SU-ALOHA, MS-ALOHA or Ad hoc mode provided in an embodiment of the present invention, Including two processes: channel occupancy process and channel maintenance process.In the embodiment of the present invention, D2D is determined by Ad hoc mode Subframe collides, and determines particular by the channel maintenance process of Ad hoc mode.

Specifically, the information of the occupancy situation of each D2D subframe in a superframe is obtained by Ad hoc mode, according to this Information determines the occupancy situation of each D2D subframe in a superframe.For Ad hoc mode provided in an embodiment of the present invention, specifically Implementation is referred to the description of above-described embodiment, and details are not described herein again.

For RR-ALOHA, SU-ALOHA and MS-ALOHA, the information of the occupancy situation of each D2D subframe is carried on FI letter In breath.Assuming that node C is occupied in the FI information instruction subframe k that subframe i is received by node A, node C is received in subframe j FI information instruction subframe k is occupied by node B, and the D2D that subframe k is node C receives subframe, then node C determines node A and node On subframe k resource collision occurs for B.Assuming that node C is occupied in the FI information instruction subframe k that subframe i is received by node A, and The D2D that subframe k is node C sends subframe, then node C, which determines to send in its D2D, occurs resource collision in subframe.

There are many implementations of above-mentioned steps 110.The embodiment of the invention provides following three kinds of preferred implementations.

The implementation one of step 110: resource collision information is sent to base station, which is used to indicate this section The D2D of point, which is sent, occurs resource collision in the D2D reception subframe for occur in subframe resource collision and/or this node.

Correspondingly, also receiving should if resource collision information indicates the D2D of this node to send in subframe and resource collision occurs The D2D communication resource configuration information that base station is sent, D2D communication resource configuration information include the letter of the D2D subframe of base station distribution Breath；Subframe is sent according to the D2D that the information of the D2D subframe of base station distribution redefines this node.Specifically, can be base The D2D that the D2D subframe distributed of standing is determined as this node sends subframe.

For the first implementation of step 110, D2D terminal only monitors the occupancy of D2D subframe by Ad hoc mode Situation distributes D2D resource by base station.Therefore, D2D terminal realizes the channel maintenance process of Ad hoc mode, does not need to realize letter Road occupies process.

The implementation two of step 110: at least one free time D2D subframe is selected；By the mark of the idle D2D subframe of selection Information is sent to base station.

In the embodiment of the present invention, idle D2D subframe refers to that the information of the occupancy of the D2D subframe received indicates The state of the D2D subframe is the subframe of idle state.

In the embodiment of the present invention, the identification information of D2D subframe can with but be not limited only to be D2D subframe number.

Correspondingly, also receiving the D2D communication resource configuration information of base station transmission, the D2D communication resource configuration information packet Include the information of the D2D subframe of base station distribution；The D2D of this node is redefined according to the information of the D2D subframe of base station distribution Send subframe.Specifically, the D2D subframe that the base station is distributed can be determined as to D2D sends subframe.

The implementation three of step 110: on the identification information that the D2D reselected by Ad hoc mode is sent to subframe Offer base station.

Correspondingly, determining that D2D is sent in subframe after generation resource collision by Ad hoc mode, request base station is carried out Before the control of D2D resource allocation, D2D is reselected by Ad hoc mode and sends subframe.

For the third implementation, i.e., channel occupancy and channel maintenance are carried out by Ad hoc mode, and send in D2D After resource collision occurs for subframe, the D2D that Xiang Jizhan reports this node to reselect sends subframe.

It should be pointed out that above-mentioned three kinds of implementations of step 110 can cooperate implementation, and these three implementations point It can not be in conjunction with any implementation of above-mentioned steps 100.

Above-mentioned three kinds of implementations of step 110 can cooperate implementation to refer to, different D2D terminals, reality that can be different Existing mode.

D2D terminal is also to base station reporting position information.The embodiment of the present invention provides a kind of preferred side of reporting position information Formula.Based on above-mentioned any means embodiment, preferably, determining this according to the corresponding relationship in geographical location and electronic map region The corresponding electronic map region in the geographical location of node, the electronic map that this node and base station are shared be divided into it is multiple electronically Graph region；The identification information (i.e. location information) in determining electronic map region is sent to base station.Wherein, geographical location and electronics In the corresponding relationship of map area, electronic map region is the electronic map region for the electronic map that node is shared with base station.Its In, electronic map can be what node and base station were obtained from same source, or in D2D base station access by terminal, from base station Downloading.Wherein, the identification information in electronic map region can be the number in electronic map region.

Method provided in an embodiment of the present invention base station side implementation as shown in Fig. 2, specifically including following operation:

The D2D resource allocation that step 200, receiving node are sent controls request, and D2D resource allocation control request is node It is determined by Ad hoc mode and is sent after resource collision occurs in D2D subframe.

In the embodiment of the present invention, node, that is, D2D terminal.

Step 210 controls request progress D2D resource allocation control according to above-mentioned D2D resource allocation.

Request is controlled for different D2D resource allocation, carries out the specific implementation of D2D resource allocation control also not Together.The embodiment of the present invention is illustrated with three preferred implementations.

The implementation one of base station side: the resource collision information that receiving node is sent, resource collision information are used to indicate this The D2D of node, which is sent, occurs resource collision in the D2D reception subframe for occur in subframe resource collision and/or the node；If money The D2D that source collision information indicates the node, which is sent, occurs resource collision in subframe, distributes D2D subframe for the node；To the section Point sends D2D communication resource configuration information, which includes for the letter of the D2D subframe of node distribution Breath；If the D2D that resource collision information indicates the node, which is received, occurs resource collision in subframe, redistributes generation resource and touch The D2D hit receives subframe and/or distributes D2D subframe again for the node of resource collision occurs in the D2D subframe.

The implementation one corresponds to the implementation one of the terminal side D2D step 110.

In the embodiment of the present invention, for node distribute D2D subframe implementation there are many.Preferably, being sent according to node Resource collision information and node location information, for node distribute D2D subframe.

Specifically, determining the node that resource collision occurs according to resource collision information, optionally, determine that resource, which occurs, touches The D2D subframe hit；Free time D2D subframe is distributed for the node, if without idle D2D subframe, according to the location information of the node, With the location information for the node for occupying each D2D subframe, determines and occupied at a distance from the node not less than the node of given threshold D2D subframe distribute to the node.

Resource collision is carried in the embodiment of the present invention, in resource collision information and indicates information, if also carrying the mark of node Know information, then determines the node that resource collision occurs according to the identification information；If not carrying the identification information of node, but take With the identification information of D2D subframe, which can be determined according to the occupancy situation of the D2D subframe of self maintained；If carried The identification information of node, but the identification information without carrying D2D subframe, can also be according to the occupancy of the D2D subframe of self maintained Situation determines the D2D node.

In the embodiment of the present invention, the node of idle subframe and each D2D subframe of occupancy is the D2D subframe according to self maintained Occupancy situation determine.

In the embodiment of the present invention, location information is periodically acquired, or resource occurs in D2D terminal D 2D subframe After collision, obtained from D2D terminal.

In the embodiment of the present invention, preferably, location information is the identification information in electronic map region.

The implementation two of base station side: the identification information at least one D2D subframe that receiving node is sent；According to receiving D2D subframe identification information, for the node distribute D2D subframe；D2D communication resource configuration information is sent to the node, D2D is logical Letter resource allocation information includes for the information of the D2D subframe of node distribution.

The implementation two corresponds to the implementation two of the terminal side D2D step 110.

It can be node from the D2D subframe that the identification information of the D2D subframe received indicates in the implementation two Distribute D2D subframe.Both it can be randomly assigned, can also be distributed with combining position information, can also be distributed using other modes, this hair It is bright that this is not construed as limiting.If combining position information distributes, it is referred to aforementioned implementation one.

In the implementation two, the D2D subframe that can also be indicated from the identification information of the D2D subframe received, Yi Jiji In the D2D subframe stood according to the selection of the occupancy situation of the D2D subframe of self maintained, D2D subframe is distributed for node.Specific choice side Formula is referred to above-mentioned implementation one, and this is not limited by the present invention.

The implementation three of base station side: the D2D of receiving node sends the identification information of subframe；Subframe is sent according to D2D The location information of identification information and the node of occupancy D2D transmission subframe determines that occupying the D2D sends between the node of subframe Distance；If the distance is less than distance threshold, the D2D subframe is redistributed.

The implementation three corresponds to the implementation three of the terminal side D2D step 110.

In the implementation three, there are many implementations of redistributing the D2D subframe, such as can be with combining position information The D2D subframe is redistributed, which can also be distributed to the node that request carries out D2D resource allocation, may be used also To be randomly assigned, etc..

Based on above-mentioned any base station side embodiment of the method, the occupancy situation of D2D subframe is also safeguarded in base station.Specifically basis connects The above-mentioned any information received is safeguarded.Correspondingly, the D2D resource allocation that receiving node is sent controls request further include: connect Receive the information of the occupancy situation of the D2D reception subframe for the node that node is sent；According to the control request of D2D resource allocation to node Carry out the control of D2D resource allocation, further includes: according to the occupancy situation of information update D2D subframe.
